Ottawa Valley

The Ottawa Valley is the valley of the Ottawa River, along the boundary between Eastern Ontario and the Outaouais, Quebec, Canada. The valley is the transition between the Saint Lawrence Lowlands and the Canadian Shield. Because of the surrounding shield, the valley is narrow at its western end and then becomes increasingly wide (mainly on the Ontario side of the river) as it progresses eastward. The underlying geophysical structure is the Ottawa-Bonnechere Graben. Approximately 1.3 million people reside in the valley (and along its tributaries), around 80% of whom reside in Ottawa. The total area of the Ottawa Valley is 2.4 million ha (6 million ac). The National Capital Region area has just over 1.4 million inhabitants in both provinces. Near the City of Ottawa, the Ottawa Valley merges with the St. Lawrence Valley to the south to create a delta of flat farmland stretching unbroken from the Ottawa River to the Saint Lawrence River as far east as the island of Montreal, where the two rivers meet. The area is sometimes referred to as the "Lower Ottawa Valley," in contrast with the "Upper Ottawa Valley" west of Ottawa, but the name is not common, and most people think of the Ottawa Valley as only the upper portion. From west to east, communities in the Ottawa Valley include Mattawa, Deep River (with nearby Chalk River, the site of Canada's nuclear reactor program), Petawawa (a major Canadian military base), Pembroke (where Samuel de Champlain landed briefly), Fort Coulonge, Shawville, Renfrew, Quyon, Arnprior, Ottawa (the nation's capital), Rockland, L'Orignal, Hawkesbury, and Rigaud and Almonte, Round Lake Centre, Dacre, Douglas, Hyndford, Scotch Bush, Osceola and Barr Line.

Dunrobin, Ontario

Dunrobin is a community in West Carleton-March Ward in the City of Ottawa, Ontario, Canada. It is located about 35 kilometres northwest of Downtown Ottawa. Dunrobin lies within a valley, nestled between the Ottawa River and the Carp escarpment, and is located at 45.18° latitude and 75.55° longitude. Dunrobin is located on the former boundary between West Carleton Township and Kanata (formerly March Township). Dunrobin was amalgamated with the city of Ottawa in 2000. Dunrobin is expanding steadily with a current population of about 1,000 people. The Dunrobin Community Association defines the community boundaries as Murphy Sideroad, Constance Lake Road and Berry Sideroad on the south, the Ottawa River to the east, a line following Limestone Road to Kinburn Sideroad to Stonecrest Road to Thomas A. Dolan Parkway to Marchhurst Road on the west, and on the north by a line following Kilmaurs Sideroad to Woodkilton Road to Kinburn Sideroad to Constance Creek. Dunrobin was settled in the 19th century at the corner of Dunrobin Road and Thomas A. Dolan Parkway. The town centre comprises a community centre with outdoor recreation facilities and a number of small businesses. While originally started as an agricultural community it now serves mostly as a focal point within a larger community that has a mixed population of farmers, commuters who work in Kanata and Ottawa-Gatineau, cottagers and pensioners. Some nearby points of interest include Fitzroy Provincial Park, Constance Bay and the Diefenbunker museum. Dunrobin took its name from Dunrobin Castle near Golspie, Scotland. On September 21, 2018, a high-end EF3 tornado struck the community, damaging or destroying 60 buildings and seriously injuring three people.
